Cashew nuts lower your blood pressure with the help of magnesium present in them.
Copper is the mineral which helps your hair get that color. So if you take cashews which are full of copper content, you can get that black hair that you always wished for.
Like calcium, magnesium is also important for bone health which is the main content in cashew nuts.
Magnesium is stored on the bones surface which prevents calcium from entering the nerve cells and thus keeps the blood vessels and muscles relaxed. Insufficient amount of magnesium can lead calcium to enter the blood vessels leading them to contract. It also leads to high blood pressure, migraine headache etc.
